OriginalVoltage regulation of a matrix converter with balanced and unbalancedthree-phase loads

Abstract

This paper addresses the design, simulation and experimental validation of a voltage control for a three-phase to three-phase Matrix Converterworking under balanced and unbalanced resistive loads. The converter is based on bidirectional switches and space vector pulse width modulationis used to control their turn-on and turn-off times. Tracking and repetitive controls are designed and implemented; having this last one a majorimpact on the performance of the output voltage regulation for balanced or unbalanced loads. The experimental control setup is comprised of afield programmable gate array board, a digital signal processor and a graphics interface board.All Rights Reserved © 2015 Universidad Nacional Autónoma de México, Centro de Ciencias Aplicadas y Desarrollo Tecnológico.
